Human serum from blood or plasma fractions, process for its preparation and laboratory reagent containing this serum

摘要

A human-type serum is reconstituted from at least one residual sub-fraction resulting from the fractionation of human plasma and/or human blood and/or placental or retro-placental blood and possesses physico-chemical properties similar to those of natural human serum, particularly as regards to limpidity, colour, content of the various contituents, and electrophoretic profile. Also described are a laboratory reagent containing said serum and the process for preparing it.
